PATENT ()FFICE.

OF SYRACUSE, NEW' YORK, ASSIGIIORS TO GROUSE-I-I. "-I1\'I'I)E CQMPANY, SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK.

Application filed January To (all whom it may concern Be it known that we, CARL H. BISSELL and ELnii G. SMITH, citizens of the United States, residing at Syracuse, 1n the county not Onondaga and State of New York, have features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference ishad to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a plan view, partly broken away 01 this lamp housing.

Figure 2 is a vertical sectional View taken centrally of Fig. 1, the lamp socket being shown in elevation.

This lamp comprises generally, a body 1 having a box-like portion 2 provided with an opening 3, in its front side, and an extension 4t on its upper side; a lens carrier as a collar 5 mounted on the front side of the box and movable into and out of interlocking engagement with the box upon a lateral sliding movement of "the collar or lens support, a lens 6 carried at the outer end of said support in line with the opening 3, and a lamp socket 7 mounted in the extension 4: in position to support a lamp as an incandescent electrielamp in line with the opening 3 and lens 6.

The box portion 2 of the body 1 is here shown as cylindrical in general form and is provided with means as an internally threaded nipple 8 for connection to a conduit enclosing the service wires. The box has anoutwardly extending flange 9 around the opening 3. Such flange projects beyond the plane of the front side of the extension i and is formed with an out-turned lip 10 forming an external groove 11 around Y three sides as the upper and lateral sides of the flange 9. -The extension 4 is closed atits top, side and front and rear walls and INCANDESCENTELECTRIC-LAMP HOUSING.

opens at its bottom at the box 2 and the flange 9 projects beyond the front side of the extension.

The collar 5 is in the form oi a ring having a flange 12 on three sides thereof, which flange is provided with an inturned lip 13 for entering the groove 11 under the overhanging lip 10 of the flange 9 around the opening 3.

The collar 5 is also formed with a downwardly extending flange 1% at its lower side, which flange has a bearing face for engaging a flat bearing face 16 on the box or on a depending flan e 16 on the. lower side of the box.

The flange 12 and lip 13 extend on three sides, that is, the top and lateral sides of the collar and the fourth lower side of the collar is unprovided with such flange, thus the collar 5 is movable or slidable vertically relatively to the box and in so doing the lip or flange 13 interlocks under with the overhanging lip or flange 10 and thus-holds the collar in position on the flange 9.

The collar is permanently secured in position in any suitable manner as by a tastening member or screw 16" extending through the flan es 14 and 16 at the lower or fourth sides of the collar 5 and box 2.

The lens 6 may be either a true lens or merely a window or pane of glass, but is hold in position by a collar 17 enclosing the outer margin of the collar 5 and having an inturned flange 19 opposed to the outer edge face of the margin of the lens (3, this flange serving to secure the margin of the lens between the flange 19 and the outer edge of the collar 5. Preferably, a suitable resilient packing or gasket 20 protects the margin of the lens 6.

The collar 18 is here shown as secured or clamped in position by screws 21 extending through the collar 18 and threading into outwardly extending cars 22 on the flange 9.

The body is secured to a wall or to the car or tender in any suitable manner and, as here shown is provided with projecting cars 23 which are flush with the rear face of the body, these cars being adapted to receive bolts or screws.

This lamp or housing therefore is particularly economical and strong and watertight in construction and consists of a few parts which are rigidly secured together and which are not loosened by vibrations in the use of the lamp.

'What we claim is:

1. An electric lamp, comprising a body having a box portion formed with an open ing in its front side, and an extension at its top, the extension having closed top, side, front and rear walls, and opening at its bottom into the box, the box being formed with an outwardly extending flange around said opening, a detachable collar mounted on the flange, the flange and the collar hav ing means for interlocking upon a lateral movement of the collar relativelv to the flange, said collar having means for carrying a lens and a lamp socket mounted in the extension and in such position that the lamp is in line with the opening, lamp socket and lens. I

2. An electric lamp comprising a body having a box portion formed with an opening in its front side, and an extension at its top, the extension having closed top, side,

front and rear walls, and opening at its bottom 1nto the box, the box belng formed with a forwardly extending flange around -;said opening, said flange having an angular overhanging lip at its free edge, a collar having an lnturned hp around three sides thereof and arranged to interlock with the overhanging lip of said flange upon a sidewise sliding movementofthe collar, a lens carried by the outer.v end orrhe collar in line with said opening, ian d a lamp socket mounted in the extension in position to support a lamp 111 line withthe opening and the lens substantialb as and for the Jur- V pose specified. V

3. An electric lamp comprising a, body having a box portion formed with an opening in its front side and an extension at its top, the extension having closed top, side 'line with said opening, the collarhaving a face at the fourth side thereof bearing on the outer face of said flange, and fastening means at the fourth side of the collar for securing the collar to the box, and a lamp socket mounted in the extension in position to support the lamp in line with the opening and the lens, substantially as and for the purpose set forth.

4. An electric lamp comprising a body having 'a box, cylindrical in general form, the box being open at its front side,.an extension mounted on the upper side of the box, the cylindrical portion of the body hav ing a forwardly extending flange aroune the opening, a collar mounted on said flange. the flange and collar having means for interlocking upon a lateral sliding movement ofthe collar, means for normally holding the collar from sliding movement, a lens support at the outer end ofthc collar in line with the opening, and a lamp socket mounted in the extensionin position to support the lamp in line with the openings and the lens, substantially zand for the pur-' pose described. i I

In testimony whereof, we have hereunto signed our names at Syracuse, in the county of Onondaga,- and State of New York, this 11th day ofDecember, 1922.
